Prison mesh, also known as prison fencing, is a type of security fencing used primarily in corrections facilities to prevent inmates from escaping and unauthorized individuals from entering. Made from high-strength steel wires woven into a mesh pattern, this type of fencing is extremely durable and difficult to cut or climb.

Techniques such as stitch welding or peening can also be employed to mitigate the inherent challenges of welding cast iron with a wire feed welder. These methods involve making short welds or applying mechanical pressure to the welded area to relieve stress and prevent cracking.
